We look at the division of 772892 by 78 
The aim is to understand the frequency of 78 in 772892.

Advancing to step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 78

Advancing to step 2:
78 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 78

Step 3:
The number 78 fits into 772 9 times, leaving a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 702 away from 772, we end up with 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 78

On to step 4:
When dividing 708 by 78, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 99.0
Deduct 702 from 708 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 78

Let's proceed to step 5:
The number 78 fits into 69 0 times, leaving a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 990.0
Subtract 0 from 69 to get 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 78

Advancing to step 6:
The number 78 fits into 692 8 times, leaving a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 9908.0
Subtract 624 from 692 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
78 goes into 680 8 times with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 9908.8
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
560 divided by 78 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 9908.87
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 9908.871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
78 can be fit into 620 7 times, resulting in a remainder of 74.
The next digit of our result is 7. 
Result so far: 9908.8717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
740 divided by 78 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 9908.87179
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
78 goes into 380 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 9908.871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 9908.8717948
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
When dividing 560 by 78, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 9908.87179487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 9908.87179487 with a balance of 1.4e-08.
